15. Convert the following using the method of dimensional analysis. Show all work and units!!!!

16 oz = 1 lb / 1 in = 2.54 cm / 2000 lbs = 1 ton
1 oz = 28.35 g / 1 ft = 12 in / 1 cm3 = 1 ml
1 kg = 2.2 lbs / 1 mi = 1.61 km / 1 gal = 4 qts
1 L = 1.06 qts / 1 mi = 1760 yds

a.  How many inches are in 45.6 meters?

45.6 m1x100 cm1 mx1 in2.54cm=1795.27→1.80x103in

b.  How many hectograms are in 250,000 milligrams?

250,000 mg1x1 hg100,000 mg=2.5 hg

c.  Determine the number of gallons of water that are equivalent to 85,000 milliliters.

85,000 ml1x1 L1000 mlx1.06 qts1 Lx1 gal4 qts=22.525→23 gal

d.  How many kilometers are in 2560 feet?

2560 ft1x12 in1 ftx2.54 cm1 inx1 km100,000 cm=0.780288→0.780 km
